Assembling DC Cable to Connector
All DC cables are equipped with water-proof direct plug-in connectors, which mate
with DC terminals at the bottom of the inverter.
The positive and negative connectors are marked with polarity symbols and should be
equipped with correctly colored cable. Red cable represents DC positive connector
and blue one represents negative.
DC Positive Connector Assembling Procedure:
Step 1: Unscrew the water-proof terminal in the following direction.
Step 2: Strip off insulation layer of DC cable and crimp cable core with hand crimping
pliers. The length of strip insulation is approximate 8mm.
Step 3: Insert appropriately sized DC cable through water-proof terminal.
Step 4: Plug cable gland into connector housing until it makes a click sound.
Step 5: Tighten the water-proof terminal in opposite direction.
